Question

true/false. raindrops fall because raindrops fall because they become large enough that gravity can pull them out of the sky. they are small compared to atmospheric molecules. they are large compared to atmospheric molecules. they roll down isentropic surfaces and can't be stopped.

Answer 1

False

Raindrops fall due to the gravitational pull of the earth. Once they become large enough, gravity overcomes the resistance of the air and pulls the raindrop out of the sky. Raindrops are relatively large compared to atmospheric molecules, but are small enough that they can be carried by air currents. Raindrops do not roll down isentropic surfaces and can be stopped by obstacles such as buildings, trees, and mountains.
